Chemical Structure
Description
7-Bromo-3,3-dibutyl-8-methoxy-2,3-dihydrobenzo[b][1,4]thiazepin-4(5H)-one (CAS 439089-27-7), molecular formula C18H26BrNO2S and molecular weight 400.37 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Bromo-3,3-dibutyl-8-methoxy-2,3-dihydrobenzo[b][1,4]thiazepin-4(5H)-one (C18H26BrNO2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 7-Bromo-3,3-dibutyl-8-methoxy-2,3-dihydrobenzo[b][1,4]thiazepin-4(5H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
